I don't know about Ellery, as you can see in that thread he/she(?) 
mentioned interest in working on that, but I don't know anything more.

As for me, I didn't work on that, nor did I plan to.
Nor am I planning to anytime soon, DDT can handle things with the 
current parser for now (bugs can be fixed on the current code, perhaps 
some limitations can be resolved by merging some more code from DMD), so 
I'll likely work on other more important features before I go there. For 
example, I'll likely work on debugger integration, and code completion 
improvements before I would go on writing a new parser from scratch. 
Plus, it gives more time to hopefully someone else work on it. :P

Unlike Walter, I can't write a D parser in a weekend... :) Not even on a 
week, especially since I never done anything of this kind before.
